As IMHO, fax detection needs callee to answer the incoming call, how should
I proceed to get a pre-recorded audio file played ("You're bout to receive
an incoming fax call") to callee while the incoming fax call is converted
into a fax file ?

My understanding of Asterisk dialplan is :
- a fax call comes in from channel A,
- appropriate extension is dialed through channel B,
- user answers and channels A and B are bridged,
- Asterisk detects the call is a fax call and then :
--- 1. stops channel B
--- 2. jumps into dialplan fax priority

Is it possible to play a message on channel B before stopping ?

Regards


makes me think that as soon as a fax is detected, the receiving channel is
stopped
